Commissioning Experience with the ATLAS Level-1 Calorimeter Trigger System
2007
The ATLAS Level-1 Calorimeter Trigger is one of the main elements of the first stage of event selection for the ATLAS experiment at the LHC. The input stage consists of a mixed analogue/digital component taking trigger sums from the ATLAS calorimeters. The trigger logic is performed in a digital, pipelined system with several stages of processing, largely based on FPGAs, which perform programmable algorithms in parallel with a fixed latency to process about 300 Gbyte/s of input data. The real-time output consists of counts of different types of physics objects and energy sums. The production of final modules started in 2006, and installation of these modules and the necessary infrastructure…
First data with the ATLAS Level-1 Calorimeter Trigger
2008
The ATLAS Level-1 Calorimeter Trigger is one of the main elements of the first stage of event selection for the ATLAS experiment at the LHC.

Which Test Artifacts Testing Service Providers should Reuse and How? Experiences from a Case Study in the Chinese ICT Sourcing Market
2011
Software testing service providers are facing new requirements to shorten service times, lower costs, and increase service customization and quality. Reuse of test artifacts is a possible solution that can help providers to meet the requirements because reuse can improve software quality and productivity. However, the extant literature does not explain in depth which test artifacts should be reused and how. This paper focuses on ICT-enabled sourcing of software testing services in the Chinese market to identify the most important reusable test artifacts. There are two reasons for this research. First, most Chinese service providers are small or medium-sized and have to overcome obstacles su…
Analysing software integration scenarios: the case of telecommunications operations software
2008
Telecom operators deploy a vast number of software systems to support their operations. Vendors of this software often integrate in their products several software systems, in order to enable innovations, minimize customer's integration efforts, etc. Different integration scenarios can be envisioned, and the issue of identifying more beneficial scenarios is of a great importance to the vendors. This paper aims at analyzing different software integration scenarios from the viewpoint of their support for innovations, and focuses on the context of telecommunications operations software. For each scenario, the overall modularity of the set of software systems is evaluated, and the expected bene…
An Information Systems Design Product Theory for Integrated Requirements, Test and Defect Management Systems
2012
Software companies need to develop high-quality products fast and with low cost. Development activities are typically distributed in different places and involve multiple stakeholders in different countries. Testing is an important way to ensure product quality but it is costly and takes ample time and resources. Sourcing testing services from specialized service providers is often the most viable option for software businesses. Flexible and effective test process management is especially vital to support the testing life-cycle when external testing service providers are involved. Yet, the extant literature provides little theoretical guidance for managing the testing life-cycle, including …
